Y50 touchpad - gestures not working

So, my Y50 had right click problems. It was very unresponsive and progressively got worse. I sent it in for repair, the motherboard and touchpad was replaced. On receiving it, the new touchpad feels great. Right and left click works. But no gestures work. Synaptics also does not detect any actual touch from the touchpad, that is, the area in the tray icon that lights up when you touch the touchpad no longer moves. Is there a specific cable that detects touch and another that connects the touchpad itself ?
